MAGNeTo-ELEC-rmc MACHINE.

SPECIFICATION forming part of Letters Patent No. 388,877, dated September 4, 1888 (No model.)

To all whoml it may concern.-

Be it known that I, WILLIAM HUMANS, of Cambridge, in the county of Middlesex and State of Massachusetts, have invented a new and useful Magneto-Electric Maehine,of which the followingis a specification, reference being had to the accompanying drawings, making a part hereof, in which-- Figure l is a cross-section on line xx of Fig. 2, which is a plan, and of Fig. 3, which is a bottom plan with the bottom removed, illustrating one form of my machine. Fig. 4 is a plan illustrating the top cover, G. Fig. 5 is adetail showing one-half ofthe cover G. Fig. 6 is a detail showing the handle, its sleeve,and one of the gears in side elevation. Fig. 7 illustrates onepart of the washer which surrounds the sleeve of the handle. Fig. 8 is a diagram for illustration. Fig. 9 is a section, and Fig. 10 a plan of a modified form of my apparatus.

My invention is mainly a case which is composed of a series of permanent magnets arranged to form a permanent compound magnet,in combination with an armature arranged within the case, and suitable means for revolving the armature and connecting its coil with the line-wire, my device being a substitute for both the ordinary push-buttons and the battery now employed with them, for bells or other signals are operated by my device without the expense and care of batteries.

The case A of my device is composed of a number of permanent magnets, l, 2, &c.,held together, like pole to like pole, (and this, although of my invention, is not here described or claimed, as it forms the subject-matter of an application for patent filed by me, Serial No. 172,432.) Within this case are two polepieces, a c, which are shown as held in place by means of the screws a', which pass through lugs on each magnet, and also through the polepieces and nuts a". The ends of these screws a project sufficiently to receive the nuts a3, by which the bottom a* is heldin place, as shown in Fig. 9, in which B is a hoop and G a cover, all described in my application for patent above referred to.

The armature B is of the Siemens type, but is also new in its construction, but is not here claimed, as it forms the subject of au application filed by me, Serial No. 172,433, the end pieces, b b, being recessed into the armature and held by cross-rods b', and the crosspieces bl b3 serving to support thejournals of the armature and being held together by the cross-rods b4, both these features being described and claimed in the applications referred to.

The bridge Z)2 has uponit a tubular post, b5, which is the box or bearing for onejournal of the'arrnature, as clearly shown in Fig. 9. This tubular post has a sleeve, 57, upon it to which f the gear d is fast, and to which, also, the shoe d of the crank D is fast. The gear (l meshes with pinion di, which is fast to gear d3, which latter gear meshes with the pinion i on the armature-shaft. By this feature of myinvention I am enabled to make the axis of the crank in line with the axis of the armature and yet cause the armature to revolve many times for each revolution ofthe crank.

One end of the coil on the armature is in electric connection with the armature and the other end with the electrode f, and the electrode fis held out of contact with the electrodef/ by the spring f2, but of course is electrically insulated from the spring f2. The line Z is kept closed and the magneto machine ont ofline by making the electrodef in the form of a spring with a pressure against the electrode f3,- but when the armature is revolved to induce currents in the line the pressure of the fingers on the crank D moves the armature so as to bring the electrode f in contact with f', and also to break contact between f and f3, thus throwing the currents onto line by means of the branch Z.

In the diagram, Fig. 8, I have shown two generators and two signals in one line in order to illustrate clearly this feature of myinvention,which consists in the combination of the armature-coil with the line-wire by means of an electrode fast to the armature, but insulated from it, and in electric connection with the armature-coil, and a second electrode connected to line but out of contact with the insulated electrode on the armature until the armature is moved endwise against the force ofa spring, this spring acting to break contact between the armature and line-electrodes as soon as the armature is left free.

I have shown the crank D hinged to the shoe d and bearing upon a spindle fast to the upper journal of the armature, al1 so arranged that when the fingers are applied to the crank handle q the armature will be moved endwise,and thereby the armature-coil be connected to line by means of the electrodesff, as above described. The shape of the handle shown in Fig. lis especially devised for this purpose, for it is practically impossible when the handle is shaped as shown to revolve the armature without pressing it in and thereby forcing electrode f against electrode f', and also forcing eleetrodef away from electrode f3. The stop d* prevents the crankDfrom movingtoo far away from shoe d.

In Fig. l I have shown my apparatus constructed to be inserted in a recess in the wall of the room, or the like, by making a flange, g, around the top of the magnetic box or case, this flange being preferably in two parts integral with the upper magnets, l and 2, as shown; but it may of course be made separate and properly secured to the magnetic box or case. This is an important feature of my invention, the novelty of which resides in a permanent magnet whose component magnets form a niagnetic box or case, and which has a flange or its equivalent around one end, whereby it may 1 be fitted into and held in ay recess in the wall with its exposed flanged end nearly ush with the wall. This form of my apparatus is especially desirable where buildings are to be permanently fitted up with electric signaling apparatus, for the permanent magnet has heretofore been the bulkiest and most unsightly part of the magneto-instrument, while by my construction the magnet is mainly or altogether out of sight.

Another feature of my invention consists in recessing the front piece of the apparatus, as

shown in Figs. l and 9, the walls of the recess serving as a guard to prevent accidental injury to the crank. I have shown the crank in a recess in the outer magnets, 1 2, but it will be clear, as before, that the magnets l 2 may be replaced by a non-magnetic moldboard.

What I claim as my invention isl. In combination with the armaturccoil, a magneto-machine, and the line, an electrode on but insulated from the armature, a second electrode connected with the line, and a spring by which the two electrodes are held out of contact until the armature is moved against the force of that spring, substantially as described.

2. In combination, the armature B', electrodes ff', springfz, and electrodefs, whereby the armature-coil is out of line and the line is unbroken unlil the armature is moved against the spring, when the armature-coil is brought into line, all substantially as described.

3.k In a magnetomachine, the crank D, in combination with shoe d and armature B', whereby when the crank is turned the armature is moved endwise as well as revolved,

substantially as and for the purpose specified.

4. In a magneto-machine in which the cir cuit is closed by manipulation of the crank or handle of the machine, a knob which is smallest at the outer end and largest at the inner end, whereby when the fingers are applied to turn the crank the knob is also moved toward the machine.

5. In a magneto machine, in combination, the crank, theA armature, gear d, pinion d2, gear d, and the armature-pinion, the axis of the WILLIAM HUMANS.
